United States Patent FLEXIBLE SELF-SEALER OILER AND FLUID DISPENSER This invention relates to a flexible fluid dispenser designed for restricted pressure fluid discharge.

The object of my invention is to provide special fluid dispenser units suitable for hand operation, formed of flexible material throughout, and adaptable for restricted discharge by slight hand pressure applied to the wall sections.

Another object is to produce a hand fluid dispenser formed of a resilient fluid container provided with an adjustable flexible discharge tube leading therefrom adaptable for operation from any angle.

Another object is to provide a flexible fluid dispenser that is transparent throughout, and is provided with a self-sealing capillary discharge tube adjustable to any position.

A further object is to provide a flexible fluid dispenser adaptable to variable fluid flow, subject to regulated outlet restrictions, operative from any dispenser position.

A still further object is to produce a flexible hand fluid dispenser unit that is simple in construction, easily and efliciently operated, and that can be manufactured at a very low cost.

These several objects are attained in the preferred form by the construction and arrangement of parts as are more fully hereinafter set forth.

Similar parts on all drawings are marked by similar numerals or letters.

Fig. 13 is a similar View of a modified discharge tube, very similar to Fig. 12, except provided with an external coil spring slidably mounted over the tube and fixedly anchored in plug body, andfor the same purpose as the spring wire in Fig. 12.

In general, the fluid dispenser A comprises a closed, sealed fluid container 1, of any suitable size and design, formed of flexible, resilient material, and is provided with a suitable closing stopper plug 2 formed with a tubular recess therethrough within WhlClhiS mounted a flexible discharge tube 3 tightly, but adjustably fitted therethrough. The flexible discharge tube being extended to the fluid container bottom section, and preferably coiled within the chamber recess, the outer tube end being projected above the stopper plug and curved back to, and mounted on, the plug sealing pin. After the container chamber is filled with the chosen fluid, and the discharge tube removed from the plug seal pin, the dispenser is operated by applying external pressure on the resilient container walls, regardless of the dispenser position. The fluid discharge is regulated by the size of the tube channel, or restricted nozzle unit mounted in the tube opening.

While my device is adaptable to many fluids, and uses, it is especially applicable, and is herein illustrated and defined as a special hand oiling unit for machinery, or for hair hand shampoo applications, or for other purposes where a light, restricted fluid dispensation is required.

I will now describe more fully the detail construction of my device, referring to the drawings and the marks thereon.

The fluid container 1, when adapted as a hand oiler unit, may be of any suitable size, or body design, for convenient hand seizure, preferably bottle shape, adaptable for hand pressure operation, herein illustrated as either cylindrical or elliptical (Figs. 3 and 8), and is made of flexible, resilient material, preferably plastic and transparent, or other similar resilient materials. The container l. is designed with an extended cylindrical neck section projected from the upper container end, symmetrically positioned thereon, the container walls always remaining flexible and resilient at all times.

Within the container neck section t is mounted a suitable stopper plug 2,. or cork unit, also preferably made of plastic material, or suitable hard rubber, formed with flanged top a andprojected plug body I1 for tightly fitting and sealing same Within the container neck opening. The

stopper plug 2 is designed with a small tube recess 0 therethrough, also with a tube seal pin recess e extended within the top plug section. Within the tube recess c is mounted an elongated flexible discharge tube 3, preterably a capillary tube unit, tightly, but adjustably fitted therein, said tube also being made of flexible, transparent material, and is projected within the container chamber, extended to the chamber bottom, or coiled therein, as indicated in Figs. 1 and 6 of the drawings. The outer tube end is projected from the stopper plug 2, curved and returned to the plug seal pin 5 projected from the plug surface and rigidly mounted within the plug recess e. When the tube 3 ispressed over the seal pin 5, the fluid dispenser A is. locked, sealed, and wholly inoperative. The capillary attraction of the discharge tube 3 will prevent leakage therefrom even when left unsealed, or placed on the container side, although full fluid discharge may be made from any container position when the tube 3 is removed from the seal pin as illustrated in Figs. 2 and 7, if pressure is applied to the container resilient walls. For reaching inaccessible places within compact machines, the discharge tube 3 may be elongated by readjustment through the stopper plug recess 0, although complete removal therefrom is prevented by the tube end button 1 expanded thereon, or such extension may be accomplished by extensive coiling of the tube within the container as indicated in Fig. 11 of the drawings. For a restricted fluid flow from the discharge tube end, a small tubular nozzle 6 may be inserted within the tube end opening as indicated in Figs; 7 and 9, but when so installed the stopper seal pin 5 may be removed from its recess e, and the projecting nozzle 6 inserted therein for tube sealing. The operation is exactly the same as in the former case. For further fluid flow restriction when required, a fine Wire section g may be inserted within the nozzle opening, as indicated in Fig. of the drawings.

In special cases a straight extended tube section is necessary, for entering'closed compartments, a fine spring wire 7 may be inserted internally within the discharge tube 3, as indicated in the Fig. 12, or a fine closed coil spring 8 may be mounted over the tube 3, externally, preferably fixedly mounted within the stopper plug recess, and extended to the outer tube end, as illustrated in the Fig. 13. The spring reaction, in either case is the same and will retain the outer tube end in a straight position, whenever released. Neither the spring wire '7 nor coil 8 will affect the dispenser operation in any manner.

When my fluid dispenser is adapted to hair shampoo use, the capillary discharge tube 3 is preferably made of greater length, and an added button end f formed on the outer tube end, as illustrated in Fig. 4 of the drawings, the buttoned end being held between the operators fingers, Within the massaging hand during the hair treatment, said dispenser being held in the opposite hand for applying discharge pressure thereto as required for needed shampoo fluid.

. When the dispenser is used for oiling delicate instruments such as Watches, or similar units, a very restricted, fine, capillary tube section 3a is especially adaptable for restraining the fluid flow, inasmuch as excessive oil within delicate hearings will tend to lock, instead of lubricate the bearings. It has been determined that by utilizing very small plastic tube 3, subjected to special heat treatment and softening, the tube may be stretched and reduced in diameter to a small thread-like section and still retain the capillary tube channel opening of a hairlike dimension, still operative for fluid flow under light pressure, although the capillary attraction will prevent gravity flow therethrough. When the reduced section h is extended from the outer end of tube 3, by continuation of the tube body, or joined thereto as indicated in Fig. 9, the container fluid may be slowly forced therethrough in extremely small particles by container wall pressure as previously described, sufficient for fine restricted instrument oiling. The capillary tube being flexible may be I conveniently moved to any instrument part.

While my resilient fluid dispenseris herein illustrated as especially adapted as an oiler, or a massage unit, it is to be understood that it is also applicable, and included herein,-when enlarged in size, or design, and applied to other purposes such as storage containers etc., where small quantities of fluid are required therefrom, and even though the capillary attraction within enlarged tubes may be reduced, as the reaction and operation still remain the same, and are included herein.
